In this study, we correlate diffusion connectivity metrics of the corticospinal tract with clinical behavioral scores in children with cerebral palsy undergoing autologous cord blood stem cell treatment. In diplegic and quadriplegic patients, total tract volumes were shown to have a significant inverse linear correlation with the disease severity scores. In hemiplegic patients, the fraction of the affected tract volume generally tends to decrease with greater disease severity, but also suggests cases of possible functional compensation by the unaffected tract. Standardized quantitative DTI will furthermore help characterize causes and effects of cerebral palsy manifestations and the treatment response mechanisms.
